The POT of a Casting

The POT of mana used to create and power a cantrip, spell, or ritual is most commonly drawn simply from the surrounding Ambience at the site of the casting, but the saturation of mana in the Ambience of any given location can vary, sometimes widely. The GM must determine this ahead of time – at least by the beginning of any tactical situation (as applicable).

As it is used in a given location it also declines, as well, requiring time to flow back in and return to its previous level, as discussed under the heading “The Ambience.” 

Mana released from a mortal source (objects that contain power naturally, see “Supplemental Sources of Mana” in the “Wizards’ Tool Box”) in the immediate vicinity of the casting just prior to beginning to cast raises the effective POT of the local Ambience by the POT of mana released

This lasts only for [(MGT + TR) ÷ 4] minutes, unaffected by any charms castor begun during that time, after which time it declines by one (1) point per minute until the POT of the Ambience has returned to normal. 

 

Cantrip: the practitioner may draw up to [(MGT + charm SL) ÷ 4] points of POT, OR up to (POT of local Ambience, GM’s discretion), whichever is less, into any given Common Sphere charm within the normal/base CTM.

For Noble Sphere charms, the practitioner may draw up to [(MGT + charm SL) ÷ 6] points of POT, OR up to (POT of local Ambience, GM’s discretion), whichever is less, within the normal/base CTM.

For Sovereign Sphere charms, the practitioner may draw up to [(MGT + charm SL) ÷ 8] points of POT, OR up to (POT of local Ambience, GM’s discretion), whichever is less, within the normal/base CTM.

 

Spell: the practitioner may draw up to [(MGT + charm SL) ÷ 2] points of POT, OR up to (POT of local Ambience, GM’s discretion), whichever is less, into any given Common Sphere charm within the normal/base CTM.

For Noble Sphere charms, the practitioner may draw up to [(MGT + charm SL) ÷ 4] points of POT, OR up to (POT of local Ambience, GM’s discretion), whichever is less, within the normal/base CTM.

For Sovereign Sphere charms, the practitioner may draw up to [(MGT + charm SL) ÷ 6] points of POT, OR up to (POT of local Ambience, GM’s discretion), whichever is less, within the normal/base CTM.

 

Ritual: the practitioner may draw up to (MGT + charm SL) points of POT, OR up to (POT of local Ambience, GM’s discretion), whichever is greater, within the bounds of its normal CTM.

For Noble Sphere charms, the practitioner may draw up to [(MGT + charm SL) ÷ 2] points of POT, OR up to (POT of local Ambience, GM’s discretion), whichever is less, within the normal/base CTM.

For Sovereign Sphere charms, the practitioner may draw up to [(MGT + charm SL) ÷ 4] points of POT, OR up to (POT of local Ambience, GM’s discretion), whichever is less, within the normal/base CTM.

 

IF you wish your practitioner’s charm to have a greater POT than is granted within the normal bounds of the CTM, as quoted above, the casting may be extended to give the caster time to gather the additional POT desired, as follows.

 

Cantrip: for every Pulse added to the CTM of a Common Sphere charm, the caster may add four (4) points of additional POT to the casting.

For every Pulse added to the CTM of a Noble Sphere charm, the caster may add two (2) points of additional POT to the casting.

For every Pulse added to the CTM of a Sovereign Sphere charm, the caster may add one (1) points of additional POT to the casting.

Spell: for every Pulse added to the CTM of a Common Sphere charm, the caster may add [(MGT + charm SL) ÷ 4] points of additional POT to the casting. 

For every Pulse added to the CTM of a Noble Sphere charm, the caster may add [(MGT + charm SL) ÷ 6] points of additional POT to the casting.

For every Pulse added to the CTM of a Sovereign Sphere charm, the caster may add [(MGT + charm SL) ÷ 8] points of additional POT to the casting.

Ritual: for every mileway added to the CTM of a Common Sphere charm, the caster may add (MGT + charm SL) points of additional POT to the casting. 

For every mileway added to the CTM of a Noble Sphere charm, the caster may add [(MGT + charm SL) ÷ 2] points of additional POT to the casting.

For every mileway added to the CTM of a Sovereign Sphere charm, the caster may add [(MGT + charm SL) ÷ 4] points of additional POT to the casting.

IF your practitioner has one or more objects that may be used as mortal sources of mana (see “Alternate Sources of Mana”) or that have been prepared as Touchstones, these may be tapped to draw additional points of POT.

Each object tapped as a mortal source of mana adds one (1) Pulse to the CTM, but you may use as much of its POT from it as you care to, from one point to all of it.

Up to (1 per 4 TR’s) Touchstones may be tapped in a single Pulse (added to the CTM), and again, you may use as much POT from it as you care to, from one point to all of it.

Such natural found object(s) and/or Touchstone(s) must first be spiritually attuned to the practitioner, however, before their POT may be tapped, as described under the heading “Attunement & Ownership” under the heading “The Wizards’ Tool Box.”

All supplementary sources of mana to be tapped for a casting (natural objects or Touchstone) must lie within sight and within [(MSS) + (TR)] feet of the caster, unless they are actually located on his person somewhere.

To supplement a charm’s POT without increasing the CTM, your practitioner can tap the pool of power he holds in reserve within himself (using as much of it as you care to spend, from one point to all of it).

Alternately, your practitioner can spend his own life-force in the form of Wind points, adding 1 point of POT for every point burned. 

IF a sufficient number of Wind are burned, the corresponding FTG are consumed along with the Wind, according to those rules, normally.
